Vollala A1 Mohandas Rao A1 Sudarshan Surendran YR 2007 UL http://nsj.org.sa/content/12/4/338.abstract AB The most commonly known nerve compression syndrome is carpal tunnel syndrome, in which the median nerve is compressed at the wrist. Along with the pathological processes, some of the anatomically variant structures can also compress the nerves and often leads to confusion in the diagnosis and treatment if one is unaware of such possible anatomical variants. Here, we present a case of possible median nerve compression by an additional belly of coracobrachialis and a fascial sheet from the brachialis, and we also discuss the other possible structures that can compress the median nerve.
